I have PHd in BL so I'm gonna tell you what will happen
The seme will keep the uke captive resulting in a lot of violence
The uke will eventually get used to it, he unconsciously will metamorphos into the seme's pet.
Some event will happen and seme will take a bullet off the uke
And the uke will be like oh nooo he likes me nobody ever did that for me
Then both will become possessive of each other and the uke will start wondering if the seme loves him and if he is worthy of love
Seme will confess and they will live toxicly ever after
The end
